maintainers:

description:
ImgTec Powerdown Controller (PDC) Interrupt Controller has a number of input
interrupt lines which can wake the system, and are passed on through output
interrupt lines.
properties:
compatible:
const: img,pdc-intc
reg:
maxItems: 1
interrupt-controller: true
'#interrupt-cells':
description: >
<1st-cell>: The interrupt-number that identifies the interrupt source.
0-7: Peripheral interrupts
8-15: SysWake interrupts
<2nd-cell>: The level-sense information, encoded using the Linux interrupt
flags as follows (only 4 valid for peripheral interrupts):
0 = none (decided by software)
1 = low-to-high edge triggered
2 = high-to-low edge triggered
3 = both edge triggered
4 = active-high level-sensitive (required for perip irqs)
8 = active-low level-sensitive
const: 2

description: Number of waking peripherals

First entry is syswake IRQ. Subsequent entries are 1 per peripheral.
